On April 3, 1973, Martin Cooper - a Motorola researcher and executive - made the first ever mobile telephone call from a handheld handset. The call was placed to his rival, Dr. Joel Engel of Bell Labs. The prototype handheld phone used by Dr. Cooper weighed 1.1 kg and measured 23 cm long, 13 cm deep and 4.45 cm wide.
Fast forward to 2017. The earth is 50 degrees hotter. All of the animals are dead, mankind is a total write-off, and phones are so small they can be shoved up the arse without even flinching.
I am, of course, referring to the Beat The Boss J8 - the world's smallest mobile telephone, released late last year.
Manufactured by Sonica, the J8 is just 7 cm long ("the length of a finger"), and weighs in at just 19 grams. Its features include a phone book, microphone, music player and alarm clock - and, according to user reviews on Amazon, its sole purpose is to be smuggled into prisons up the arses of inmates.
